1) We know that <DAB and <BAC are supplementary angles according to the exterior angle theorem, so we set up the following equation and solve:
105+x=180
x=75
2) Since we have the angles for <BAC and <ABC and a triangle has its total angles added up to 180, we can set up an equation to find <ABC and solve:
75+35+x=180
110+x=180
x=70
So the m<ABC is 70 degrees.
Hope this helped! Let me know if you need me to clarify anything.

Answer:
A= 3, B=-5, C=2
Step-by-step explanation:
Put them in order of leading power.
3x^2-5x+2
It would be written as “The logarithm of [number] to the base e”.
(e stands for the constant, Euler’s number.)
Answer:
21.
Step-by-step explanation:
RT and QS are diagonals of the rectangle and are equal in length.
5x + 1 = 6x - 3
-x = -4
x = 4
So QS = 6(4) - 3
= 21.
